Was the X77 a single unique style model? Was there a series of X models?
I ask because maybe 8 or 10 years ago I remember seeing one, or something very similar at one of the nearby Salvation Army Thrift Stores. I thought it was quite
striking, and looked to be in lightly used condition, though I don't think it
had the fancy speaker. I thought it was ridiculously inexpensive at less than $200.
Though I am not a musician , I had to resist the compulsion to purchase it because it was so unique and attractive.
